Description
I Oct. 1, 1929 G. CARPENTER SPARK ARRESTER Filed April 22. 1924 /7/ INVENTOR' ATTORNEYS Patented Oct. 1, 1929 PATENT OFFICE GUY CARPENTER, OF-NEW YORK, N. Y.
SPARK ARRESTER Application filed April 22,
My invention relates to the art of producing devices adapted to arresting, cooling and collecting, the solid substances accompanying the gases in the products of combustion, particularly as applied to locomotive engines and, to a large extent, follows the principle and arrangement of most of the structural elements disclosed and illustrated in my prior application for Patent No. 693,187, filed February 16, 1924. In fact, the structural elements are quite the same as in the aforesaid application, but in this invention I add an additional screen placed in a particular manner and at a particular point which functions to materially assist the ridding of the gases of solid substances, such as sparks, cinders, and the like.
In the drawings, I have shown a preferred form of construction, but I do not wish to be understood as limiting myself to this precise construction for variations may be made therein without departing from the spirit of my invention, and I do not desire to be limited in the scope of my protection, except as set out in the accompanying claims.
By reference to the accompanying drawing, my invention may be more easily understood Fig. 1 shows a longitudinal sectional view 3 of the forward part of a locomotive engine fitted out with my improved device; and
Fig. 2 shows a transverse vertical section taken on the line 22 of Fig. 1.
Referring to the accompanying drawings,
the reference numeral 10 is used to indicate the portion of the locomotive engine in which the fire tubes are situated, 11 the smoke box, and 12 the smoke stack. In ordinary constructions the smoke box is located forward of the fire tubes and the smoke stack projects downwardly in the smoke box, the lower end thereof being open, and an exhaust jet 18 is located centrally below the open end of the stack.
I box off the smoke stack 12 from the main body of the smoke chamber, by placing a partition 14 to the rear of the smoke stack, which connects with a horizontal partition 14 mounted below the smoke stack, these two 59 partitions forming the box, the jet 13 extend- 1924. Serial No. 708,148.
ing upwardly from the base of the locomotive and through the partition 14?. A cylin der 15, its forward end closed by a screen 16, projects forwardly from the box enclosing the stack 12, and opens into the said box. A second, and outer, cylinder 17 extends from the forward partition forming the box around the smoke stack to the forward end of the smoke chamber and the cylinder 18 is preferably concentric with the cylinder 15. The cylinder 17 is spaced, either concentrically or eccentrically, from the inner wall of the smoke box, and, preferably a partition 18 is placed in this space. A spiral element 19 is secured to the inner cylinder 15, its blade extending to the inner surface of the cylinder 17, said spiral element extending forwardly to substantially a line in a plane with the end of the cylinder 15. In the space between the convolutions of the spiral, in close proximity to the end of the spiral element, I have placed a screen 20 which extends from the inner cylinder 15 to the outer cylinder 17 and completely across the space formed by the blade pTf the spiral element, as clearly shown in n the inner surface of the cylinder 17, I have provided a plurality of baflies 21 and near each baffle is an opening 22, for purposes hereinafter stated, and in the base of the smoke box I have provided doors 23.
In practical operation, the exhaust jet (functioning normally) produces a very high velocity, but by my construction, the distance the gases are compelled to travel through the passage formed by the spiral element and the cylinders 15 and 17 causes the said gases and the attendant substances contained therein, to rotate at a very high velocity and with a. strong centrifugal force which effects the particles of solids in the products of combustion and consequently they are thrown outward against the inner surface of the cylinder 17, caught by the bafiies 21 and passed through the openings 22, into what I have termed my collecting chamber 24. In practical demonstration it has been shown that while this construction arrests and collects nearly all of the substances in the gases, yet I have found it advisable to place the screen 16 over the IIowever, I consider the screen outer end of the cylinder 15 and this functions to assist in collecting substances which have passed through the spiral passage. In experimenting with the construction thus far described (in the practical operation described above) I have found that the vacuum formed by the action of the jet 13 creates a pulling force which is exerted against the screen 16, pulling the gases through the screen, and such particles as still remain with the gases will be retarded in their forward movement and caught by the screen and dropped down into the collection chamber. Therefore, I now place the screen 20 between the convolutions in the spiral element, and
near the end of the spiral element, so that practically all of the substances-which are rotating at the high velocity, in passing through the spiral element and have not passed through the openings in the cylinder 17 are first caught by the screen 20, and as this screen is not in the direct path of the suction produced by the jet 13 it functions very satisfactorily for the purposes stated.
16 also advisable in this construction for thereby I am practically assured of stopping all of the solid substances before they are pulled into the stack chamber and emitted through the stack.
Having thus described my invention what I claim and desire to secure by Letters Patent of the United States, is:
1. A spark arrester for locomotives comprising an open-ended cylinder horizontally secured in the smoke b'oX advance of the smoke stack; a spiral element secured to and" surrounding said cylinder; an outer cylinder, provided with openings through the wall thereof surrounding, and secured to, the spiral element; a screen closing the forward end of'the inner cylinder; a screen between the convolutions forming the spiral element and located near the forward end of said element and extending from the inner cylinder to the outer cylinder; and battles on the inner surface of the outer cylinder, one being adjacent each of the aforesaid openings.
2., A sparkarrester for locomotive engines employing a smoke stack and a smoke chamber; a forwardand a rear partition separating the smoke stack from the smoke'chamher, the forward partition being provided with an opening; a cylinder fitted in the opening in the forward partition and projecting therefrom to near the end of the smoke box; a spiral element secured to the outer surface of the said cylinder; an outer cylinder, provided with openings through its wall, surrounding and secured to, the said spiral element, saidcylinderbeing spaced from the inner surface of the smoke box; a
screen mounted between the convolutions forming the spiral element; a second screen closing the opening of the aforesaid inner cylinder; and baffles on the inner surface of the outer cylinder, one adjacent each of the aforesaid openings.
3. A spark arrester for locomotive engines employing a smoke box with an opening in the base thereof and a smoke stack; a forward and a rear partition separating the smoke stack from the smoke chamber, the forward partition being provided with a cylindrical opening; ing and projecting forwardly therefrom; a spiral element secured to the outer wall of the said cylinder; an outer cylinder, provided with openings through its wall surrounding the said spiral element, said cylinder being spaced from the inner surface:ofthe smoke chamber; a screen mounted between the con-' GUY CARPENTER;
